Sweden's two-year experimentation with six-hour work days has concluded. Various jobs were included in the experiment, including hospital nurses. The final report will be released next month, but preliminary data suggests that the shorter work day resulted in better health, increased productivity, and less sick leave logged. Critics of the experiment argued that taxpayer dollars were being wasted on a trial that was not economically sustainable. The experiment cost the city 12 million kronor, or $1.3 million USD. The pilot programs will be continuing in other sectors throughout Sweden, including the private sector.
